There are resources such as Toal, M. F., ed. The Sunday Sermons of the Great Fathers. Translated by M. F. Toal. Vol. 1–4. San Francisco: Ignatius Press, 2000. which include parallel passages - in this case limited to the Gospels. If would be helpful to be able to bring up the Parallel Gospel Reader from the Context Menu to see the parallels in their best format for comparison. I would not mind a mechanism similar to Community Tags which puts the onus of tagging on the users. Why? Because it would allow us to also tag the extract from the Caterna Aurea to its source in Aquinas.
